Dyno comparisons.... (so we can see who has what?)
I just wanted to post this for the benifit of guys around the world trying to make sence of all the different dyno std's being used.
"The dyno used is manufactured by DynoPak and measures rwhp in PS (Japanese hp rating - PS is within 1% of hp so lets treat it as such) by directly bolting on to the rear wheel hubs. This allows for a very accurate rwhp reading as there is no hp loss from tyre slip and no hp loss from friction generated by the rotating tyre itself. Because of the elimination of these hp losses from the rwhp results, one needs to be able to compare the dynopak dyno to the other common dyno types.
To calculate the approximate flywheel hp, multiply the rwhp by the following numbers for each dyno type:
New Zealand DynoPak - 1.20 (2wd manual), 1.23 (2wd auto), 1.33 (4wd manual), 1.40 (4wd auto)
Australian\UK DynoDynamics - 1.30 (2wd manual), 1.35 (2wd auto), 1.50 (4wd manual), 1.60 (4wd auto)
USA DynoJet - 1.17 (2wd manual) 1.20 (2wd auto)
"
eg. my 472rwhp (dynapack) = around 566bhp ? which ever way hope this helps newbies and pros alike in allowing "rough" comparisons.
Take care

Hey Pete, your back.
Haven't seen you on the forum for a while.
Anyway, it'll be interesting to see what all these guys are getting and finding out how they did it so I can dream of getting close one day.
